Under the plans, which will be discussed by the International Olympic Committee starting Dec. 8 in Monaco, lobbyists would have to be part of a register and sign up to an ethics code to represent candidate cities.

The IOC’s proposal is one of 40 recommendations made public today after a yearlong consultation. Oslo last month withdrew from bidding to host the 2022 Winter Olympics, leaving only Beijing and Almaty, Kazakhstan, in the running.

Soccer ruling body FIFA’s ethics committee last week released a summary of a report into voting that awarded the 2018 and 2022 World Cup to Russia and Qatar that found some bidders gave excessive gifts and complied with improper requests.

The IOC, also based in Switzerland, was stung by a vote- selling scandal surrounding the 2002 Salt Lake City games, when 10 IOC members were expelled or resigned. Since then, the IOC introduced tighter rules on conduct by bidding cities including gift giving.

“Maybe our selection process is the gold standard but we want to make it even better,” Craig Reedie, an IOC vice president, said by phone from London.

Other recommendations include bidding cities having some of their costs paid by the IOC. London spent as much as 27 million pounds ($42.3 million) in 2005 on its successful bid to stage the 2012 games, Reedie said.

Under another proposal, host cities might be able to stage events in other countries which, for example, could remove the need to build a bobsled track for the winter games, he said.

“A lot of the time we feel that bidders are saying what they want us to hear, rather than what they want,” Reedie said.
